After receiving her B.S. degree in Mechanical Engineering with highest honors from Rensselaer Polytechnic Institute in 1987, Antoinette Maniatty went on to earn two M.S. degrees in Mechanical Engineering, one from the University of Minnesota in 1988 and a second from Cornell University in 1990, followed by a Ph.D. from Cornell in 1991. After spending one year as a Visiting Lecturer at the University of Natal in Durban, South Africa, she joined the faculty at Rensselaer in 1992. She was the Clare Boothe Luce Assistant Professor from 1992-1997. She was one of four women scientists and engineers nationwide to be awarded a Luce fellowship by the Luce Foundation in 1992. In 1993, she received a National Science Foundation Young Investigator Award. She was a member of the Defense Science Study Group in 2000 and 2001. In 2001, she was the first Loewy Visiting Professor in the Materials Science and Engineering Department at Lehigh University. Maniatty is a member of the American Academy of Mechanics, the American Society of Mechanical Engineers, Tau Beta Pi, and Pi Tau Sigma.

Research Interests and Activities

The general area of research is in the broad field of computational solid mechanics. Specific problems being currently investigated include modeling crystalline materials and inverse/optimization problems. In the area of modeling crystalline materials, work is being done to use micromechanics as a basis for modeling large strain metal forming problems. Work is also being done to model thermal stresses in thin metal films on semiconductor wafers during thermal cycles and in semiconductor crystals during growth. The other area of research involves inverse and optimization problems. This work investigates problems with either unknown boundary conditions or unknown parameters. Applications include optimization of forming processes and determining unknown boundary conditions in contact problems for modeling and predicting wear. More information can be found here.
